Abstract

Digitalization transformation in learning refers to the use of information and communication technology to improve the learning and teaching process. In the digital era, teaching materials can be accessed in electronic form. One of the electronic teaching materials that can be used is e-catalog, which is an electronic-based catalog innovation, which is easier to learn anytime and anywhere, cheap and easy to share. However, teaching materials used in learning biology in high school are mostly textbooks that have not been digitized. Various environmental problems that currently arise are not entirely derived from the development of the industrial and technological sectors, but the weak level of human literacy, including attitudes and behaviors towards the environment. This causes the relationship between humans and the environment to be less dynamic. Good environmental education can help raise public awareness about the importance of protecting the environment. Education for Sustainable Development (ESD) is considered necessary to be integrated into the curriculum content and implemented into learning. The purpose of this study is to determine the implementation and effectiveness of ESD-oriented e-catalog-based learning digitalization transformation on the concept of environmental change can improve student learning outcomes. This research method uses a Research and Development (R&D) approach, adapting the ADDIE development model. The ESD-oriented e-catalog on the concept of environmental change has a validity value of 96.40% with a very valid category. The practicality value is 94.56% with a very practical category. The effectiveness value of the N-Gain score for cognitive learning outcomes is 75.12% with a fairly effective category. This ESD-oriented e-catalog can be implemented by being used as a comparison and reference material in developing innovative teaching materials to prepare students for the 21st century.

Abstract

Melon productivity in Indonesia has been declining. Global climate change is affecting the productivity of melons. Long-term droughts have contributed to a reduction in plant growth and development. Hormopriming is an alternative to increase the germination and growth of melon plants by soaking seeds in a solution of plant growth regulators. Brassinosteroid can enhance germination and plant tolerance under drought conditions. The objective of this research is to examine the impact of brassinosteroid hormopriming treatment on the germination and growth of melon plants subjected to various degrees of drought stress. The study utilized a two-factor fully randomized design. The brassinosteroid concentrations used were 0, 0.05, 0.10, and 0.15 ppm. Media with different water capacities of 75%, 50%, and 25% Space Capacity (SC) were used to test drought stress resistance. Water capacities were examined using the gravimetric method. This study's findings suggest that treating melon plants with brassinosteroid variations can induce drought resistance in M15 melons. A brassinosteroid concentration of 0.15 ppm is the best concentration, as it can increase all parameters of plant growth and adaptation under each variation of water availability provided. The findings of this study can serve as a reference for melon cultivators constrained by dry land conditions to increase the efficiency of cultivation.

Abstract

Ferns (Pteridophyte) are members of the kingdom plantae that contribute to Indonesia's biodiversity, especially the diversity of flora. Ferns have an important role in maintaining the balance of the ecosystem. In addition to having ecological value in the ecosystem as a source of germplasm, ferns also have the potential to be useful to support people's lives. However, in fact ferns are still less well-known and receive less attention than other plants. This is because one of the reasons is that people are less familiar with ferns. This study aims to identify the types of ferns (Pteridophyte) in the mountainous area of ​​Buntu Sarong Village, Masalle District, Enrekang Regency. Data collection was carried out using the exploration method at certain points in the research location that were considered potential, then recording, documenting, identifying and classifying the Pterydophyta found. The research at the research location successfully identified and documented 16 species of Pteridophyte, namely Psilotum nudum, Lycopodium, Selaginella delicatula, Equisetum hyemale, Odontosoria chinensis, Gleichenia linearis, Adiantum sp., Christella parasitica, Aspelinum nidus, Cyathea cooperi, Angiopteris evecta, Deparia petersenii, Microsorum punctatum, Drynaria quercifolia, Microsorum punctatum, Microsorum scolopendria, Drymoglossum piloselloides. The identified Pteridophyte are classified into 13 families (Lycopodiaceae, Psilotaceae, Equisetaceae, Marattiaceae, Lindsaceae, Gleicheniaceae, Adiantaceae, Thelypteridaceae, Asplenidaceae, Chyatheaceae, Athyriaceae, Polypodiaceae) and 5 classes (Lycopodiopsida, Psilotopsida, Equisetopsida, Marattiopsida, Polypodiopsida).

Abstract

This study evaluates the optimal fixation duration using 10% potassium hydroxide (KOH) at 70°C for whole mount preparations of Pediculus humanus capitis (head lice). Accurate head lice identification is crucial for effective public health management. Specimens were fixed for 20, 25, 30, 35, and 40 minutes at 70°C, then processed through rinsing, acetic acid treatment, dehydration, and clearing before mounting for microscopic examination. Results showed that 25 minutes of fixation provided the clearest and most detailed preparations. This duration effectively achieved tissue dehydration and clarification without significant damage. Fixation for 20 minutes was insufficient, resulting in opaque specimens due to incomplete KOH diffusion. Conversely, 40 minutes of fixation caused over-fixation, leading to tissue damage and poorer color quality. The study underscores the importance of finding the right fixation duration. While shorter times are inadequate, longer durations can degrade specimen quality. A 25-minute fixation at 70°C is optimal for balancing clarity and structural preservation, improving head lice identification. This method enhances the quality of whole mount preparations and provides practical guidance for accurate and reliable ectoparasite examination in clinical and research settings.

Abstract

This study aims to determine the effect of the type of mushroom on the product quality of mushroom nuggets fortified with moringa leaves with organoleptic and chemical parameters and to determine the level of antioxidant activity. This study used a completely randomized design (CRD) with one treatment factor (type of mushroom). The mushrooms used are oyster mushrooms, straw mushrooms, and enoki mushrooms. The result showed that all samples of mushroom nuggets were acceptable to the panelists, with levels of preference ranging from neutral to favorable. Mushroom nuggets fortified with Moringa leaves have a protein content of 14.90-15.51% and a fat content of 8.78-9.68%. The results of the data analysis showed that the control nuggets were significantly different from all the nuggets treated with different types of mushrooms in the parameters of aroma, taste, and texture. However, the treatment of the nuggets with different types of mushrooms did not show significant differences in the parameters of aroma, taste, and texture. The effects of different types of mushrooms on the protein and fat content of the nuggets were not significant (p > 0.05). The IC50 value of the antioxidant activity of mushroom nuggets fortified with Moringa leaves ranged from 5,500 ppm–34,547 ppm, with a very active category.

Abstract

Eco-enzyme is a mixture of organic fruit peel waste fermented with a mixture of brown sugar and water. It can be used as organic fertilizer. The aim of the research is to find out how eco-enzymes help literacy and numeracy in the growth of mustard greens (Brassica chinensis). Eco-enzymes are made with a composition of 10:3:1: 10 liters of water, 3 kilograms of vegetable waste or fruit peels, and 1 kilogram of brown sugar. In a fifteen liter plastic container, dissolve brown sugar in water. Then, add the skins and vegetable waste, and cover tightly and ferment for three months. Mustard seeds are sown and planted in polybags. Watering is done with water every day; watering with eco-enzyme solution is carried out once every three days. The amount of eco-enzyme used is 0 ml, 7.5 ml, 15 ml, and 22.5 ml in one liter of water. The parameters measured for mustard plants are height (cm) and number of leaves (sheets). The research results showed that the application of eco-enzymes as organic fertilizer at a concentration of 7.5 ml had a positive impact on the height and number of leaves of mustard plants, but had a negative impact on eco-enzyme concentrations of 15 ml and 22.5 ml. Thus, it can be concluded that administering eco-enzymes as organic fertilizer provides the most effective effect at the level of 7.5 ml

Abstract

The integration of digital technology into education is rapidly expanding. However, the use of technology in learning is often uneven. Limited literature on Schistosomiasis among students contributes to a lack of understanding about this disease. This study aimed to develop a valid, practical, and effective e-module for identifying Schistosoma japonicum worm eggs in human feces in North Lore District, Central Sulawesi. The ADDIE model was employed for the e-module's development, which included stages of needs analysis, design, development, and evaluation. The media and material validity test yielded highly valid results. The e-module's practicality was assessed as highly practical for use in teaching. The effectiveness of the media was determined to be highly effective, with an n-gain test score of 0.76, indicating a high level of learning. Based on these findings, the e-module is deemed valid, practical, and effective for use in biology education. This study is anticipated to be a reference for future researchers developing similar products in other biology subjects.

Abstract

The Sunda pangolin, also known as Manis javanica, is a vulnerable mammal that can be found in Java, Sumatra, and Kalimantan. Unfortunately, due to hunting, poaching, land changes, and forest fires, particularly in Kalimantan, this species is now categorized as endangered on the IUCN Red List. To support conservation efforts and sustainability of the Sunda pangolin, it is crucial to gather more evidence about its ecological study and habitat. Therefore, this study aimed to determine the characteristics of the habitat and distribution of the Sunda pangolin in the Bukit Tangkiling Nature Park, Central Kalimantan. We surveyed between February and June 2022 using a Visual Encounter Survey (VES) combined with burrow count methods and camera traps. The survey included vegetation, potential nest and prey, and abiotic factors for the Sunda pangolin. We found a total of two individuals using a camera trap in plot 1 and direct observation in plot 3. Additionally, we located five potential Sunda pangolin nests. According to the distribution map, the Sunda pangolin can be found in hilly and valley areas, with an estimated population of 7.14 individuals/Ha. Vegetation analysis revealed an importance value index (IVI) of 148.84% for Acacia mangium. Based on PCA results, the abiotic factors of air and soil humidity support the existence of the Sunda pangolin and its nests. We also identified eight species of Hymenoptera and one species of Isoptera, which are potential food sources for the Sunda pangolin. Overall, this study provides essential information to support conservation efforts and sustainability of the Sunda pangolin in Kalimantan.

Abstract

Cleome rutidosperma DC is a plant native to tropical Africa, India and Indochina, and it has become an invasive weed plant introduced to Indonesia, especially on the islands of Sumatra, Kalimantan, Java and the Lesser Sunda Islands, including Lombok, to the Australian continent. C. rutidosperma belongs to the Brassicaceae order which has cleistogamy flowers. The aim of this research is to determine the anatomical development of the C. rutidosperma anther. This observation was carried out in April-June 2024, at the Advanced Biology Laboratory, Faculty of Mathematics and Natural Sciences, Mataram University, Lombok. The samples used are flower buds of C. rutidosperma which are divided into 7 phases of development. The research results shown that anatomical structure of the anther of C. rutidosperma plants were analyzed descriptively. The results include various developments of flower buds, anther development, anther transverse slice preparations of each phase of development and anther locus of each development of C. rutidosperma plants presented in the form of images and descriptions. The results were obtained that there were changes in the structure of the anther tissue in each phase and this occurs along with the development of pollen. As the anther phase increases, the structures that make up the anther support the release of mature pollen.
